Bertha Benz not only invested her dowry in the invention of the world’s first motorized carriage, which she and her husband, Carl labored over for years; she’s also the chief designer, mechanic, and tester of the machine. Now, however, with the moguls who promised to back the machine withdrawing their support, Carl is ready to throw in the towel. Bertha knows that to give up would not only bankrupt the Benz family, but that it would also ruin everything they’ve worked for and their marriage. Ignoring the cynics and the men who ridicule her, Bertha takes matters into her own hands. What Bertha doesn’t know is that Carl is on the cusp of making a deal with their nemesis. She is not only risking her marriage and life’s work, but is also up against her husband’s doubt and duplicity, the bias of every man she knows—and the clock.
